Xceed Zip for x64
$899.95

Flexible, and unbelievably reliable and mature, with a 20-year track record. Updated and improved often, and backed by a responsive support and development team whose sole ambition is your complete satisfaction.

The only Zip library compatible with all the latest updates to the Zip archive format, including UTF-8 to support all characters in filenames, and LZMA for WinZip 12+ compatibility.

An easy to use ActiveX/COM data compression library built for the x86-64 architecture. You name the feature, it does it. Zip, unzip, updating, converting, disk and memory streaming, AES encryption, no 4GB or file limit, various compression algorithms, filtering, split/spanned/self-extracting zip files, and much more.

Technically superior

The library is a fully self-contained DLL, written with ATL 3.0 and with no external dependencies, STA/MTA multi-threaded apartment models, Unicode file and I/O calls, and more. Use it as an ActiveX/COM control, or access it as a standard 64-bit DLL through its exported API.

Advanced capabilities include non-blocking methods for background operation, wildcards that work even for folder names, renaming files in a zip file without unzipping then rezipping, etc.

Trusted

Updated and improved for over 20 years, used in applications everywhere, you can trust it to create robust applications that execute error-free with any kind of input data.

Appreciated by top developers

“We’ve been using Xceed Zip for some time now, originally for an archiving utility, but now for various other utilities. It has met all our requirements! I’ve found it easy to use, and the help contains good examples, which is pretty rare to find these days.”

Robert Copeland, Talgentra Ltd (Auckland, New Zealand)

“I use Xceed Zip for my projects. I love this component and it does save me lots of unnecessary hassles. On top of the high quality components that Xceed provides, I also had chances to work with their technical support team. They are extremely nice people with solid knowledge and they were able to answer all of my questions. I believe that’s one of Xceed’s strongest selling point besides the software itself and I’m confident that I will continue to count on Xceed’s team for my future needs.”

Michael Wu, CSC @ BHP Billiton (Houston, Texas, United States)

“Our program has been running for something like four years without any problems, delivering 4k packets of compressed information to up to 100 users at a time using Xceed Zip and uncompressing them for display in .25 of a second! In all that time we have not had one data error thanks to your superb compression software – and of course my superb use of it!”

Barry Harkcom, I.T.Consultant, Jones Lang LaSalle (United Kingdom)

Features

ActiveX/DLL technology

Built for the x86-64 processor architecture. A version for the IA-64 processor architecture is also available on request.

A single fully self-contained COM object and ActiveX control written with ATL 3.0.

Supports the BZip2 (BWT) compression method for 15% to 20% better compression than Deflate on many popular file types, especially XML data.

The only library to provide WinZip 12 compatibility, supporting the LZMA algorithm for improved compression in certain situations. Note: Zip files using WinZip 12’s special JPEG recompression feature are not supported.

UTF-8 character encoding in headers for improved support of international characters in filenames and comments is provided.

Filter out files during a zip file update, merge, or conversion based on any file attributes or parameters.

Set the date of the archive file to the most recent date among the files it contains.
